Create a unique Entry ID for your metadata record (for example, AAS_1234_CTD). The Entry ID can be up to 80 characters long and can contains letters, numbers, hyphens, underscores and periods.

You can find out more about the Entry ID in the DIF Writer's guide .

We recommend that you log in before completing a metadata record - this way your "in progress" metadata records will be saved for you to complete later.
If you do not log in you will need to complete your metadata record in one session
